What MailCharts and Obsession are
MailCharts: email and SMS campaign intelligence
As of 11 November 2026, MailCharts’ home page is headed “Email and SMS Campaign Intelligence” and presents it as MailCharts from Validity, offering “competitive intelligence, industry insights, and inspiration for email and SMS”. It describes its method plainly: “We signup, trigger, collect, and classify thousands of ecommerce email journeys.” Its tools include email and brand search, comparisons, journeys, lists, reports and exports, and it says over 10,000 brands and agencies use it.
Its agencies page says “We’re already tracking 30,000+ companies so you can go in and find the examples you need from Day 1”, and pitches visualisations, campaign examples and benchmark reports for client presentations. Its pages publish no price: the home page says “Contact us to get started”, and its pricing address redirects to a Validity page that lists no MailCharts plan. Its pages don’t describe adding a company you name, member prices, trial limits, cancel flows or an API.
Obsession: any company you name, past the sign-up
Obsession collects what companies show only to customers, step by step: their screens, emails and texts, member prices, trial limits, quotes and cancel offers, each dated with a screenshot. Teams and AI agents look up any company through the API or MCP, and a company not yet covered is added on request. The emails sit beside everything else the company shows a customer, so a welcome code, the price after it and the offer to stay are in one record, kept for as long as you follow the company.

When to use MailCharts, and when to use Obsession
- Use MailCharts to plan campaigns from a wide library: Black Friday examples across ecommerce, how a category’s welcome emails look, or a benchmark slide for a client.
- Use Obsession for the companies you name, whether or not any library covers them: your 10 closest competitors, the brands an agency is pitching, a software company’s trial. It keeps every email and text they send a new customer, plus the member price, the trial limit and the save offer, each dated.
- Use Obsession in your own tools. Each fact reaches your agent over MCP, a webhook or a Clay column, with the raw email and its DKIM result, so a report or an alert is built on evidence a client can check.
Using MailCharts and Obsession together
A CRM or retention team can keep MailCharts for ideas and add Obsession for the competitors that matter to its numbers. An agency can use MailCharts examples in a strategy deck and open each pitch with the prospect’s own emails from Obsession, dated, including the reminder that never came.
